Read for the information. awful at the Tube station Picking up a free newspaper at the Tube station, I see the title “Hot! Hot! Hot!”. Today, the temperature in London is expected to reach 30 plus degrees! The average high temperature in July is only 22 degrees, so over 30 is not usual for London. It’s going to be awful on the Central Line, with no air conditioning. Why did they have to invent the Tube before air conditioning? It’s just typical that my journey is on one of the oldest lines, as well as one of the deepest. It’s the hottest on the whole Tube system. 在地铁站拿起一份免费报纸，我看到的标题写着“热！热！热！”。今天，伦敦的温度预计将达到30度以上！7月的平均最高温度只有22度，所以超过30度对于伦敦来说太不寻常了。地铁中央线没有空调系统，情况会很糟糕。为什么要在空调系统之前发明了地铁？我通常上班所走的路线刚好是地铁里最老、最深的一条线。那也是整个地铁系统里最热的一条线。 thinking about work.

Because there’s no air conditioning, the temperature inside the train can reach 35 degrees! It’s lovely in the beach, but not so when you’re wearing a suit and in a crowd of passengers!
